Sumida Aquarium

I visited this aquarium over the weekend with my girlfriend during our trip to Japan. While we truly enjoyed seeing the adorable little penguins and the vibrant goldfish, the overall experience fell short of expectations. The facility itself is quite compact, and the number of exhibits feels limited, especially when considering the relatively high ticket price. In terms of value, it may not offer as much as other aquariums of similar cost. That said, there are a few highlights. The beautifully displayed jellyfish create a calming and visually stunning atmosphere. Additionally, the location is extremely convenient—perfect for those already planning a visit to Tokyo Skytree. A pleasant stop if you’re in the area, but perhaps not a destination worth prioritizing on its own.

It is my first time going in an Aquarium so I was hyped. We were already here at 9 am. The staff were very friendly. It was easy to use the ticket if you bought it on Klook. The staff will guide you on how to do it. The place is very pretty. It wasn't crowded because we were early. I really love the jellyfish 🪼. All of other animals like the seal and penguin, it was my first time seeing it in person. I love the vibes of the place. The place is not that large so you will be able to tour the place for about an hour or two hours. Overall, we enjoyed the place.

Visited Sumida Aquarium inside Tokyo Skytree Town on a breezy afternoon, and it felt like stepping into an underwater dream. The place is modern, sleek, and surprisingly peaceful despite being in such a busy spot. What really makes it special is how close you can get to the tanks—no crowded barriers, just glass and glowing blue light wrapping around you. Even if your kids don’t understand Japanese, they’ll love it here—most of the exhibits are visual and interactive, from the elegant jellyfish drifting like slow-motion fireworks to the playful penguins splashing around in their open-air pool. The layout flows beautifully, with soft lighting and gentle music that make you want to linger at every corner. There’s a small café where you can rest with a Skytree view, and the souvenir shop has some of the cutest ocean-themed gifts in Tokyo. It’s not the biggest aquarium, but every detail feels thoughtful and calm—more like an art gallery of sea life. Perfect for families or couples looking for a relaxing, beautifully designed aquarium—especially convenient if you’re already visiting Tokyo Skytree!

Sumida Aquarium is definitely worth the visit. It’s well priced and the animals are super cute and you can tell they are well maintained here. Although the aquarium is kind of small compared to others, it’s got a lot of nice exhibits and being under the Tokyo Skytree makes it convenient to visit both in the same day. The gift shop is decently priced and the gacha are really cool.

Spent a few hours here while waiting to check-in to our hotel and it was a fun time! Place is kind of small compared to other aquariums I've been to... but i think it's still worth it because of the penguins and jellyfishes!! Especially loved the display of the life stage of moon jellies! Gift shop at the exit also has tons of items you can buy as souvenirs!
